Microseconds Converter
Convert microseconds to a date, and back
The 16-digit form — PostgreSQL internals, ClickHouse, Python's `time_ns() / 1000`, and Chrome's own clock, which counts from 1601 instead.
Questions people ask
The things that come up about microseconds converters, answered plainly.
Is a 17-digit number microseconds?
Probably WebKit/Chrome time, which is also microseconds but counts from 1601 rather than 1970 — so it is about 11.6 billion seconds larger. Cookie and history databases in Chromium browsers use it.
Does JavaScript support microsecond precision?
Not in `Date`, which is millisecond-only. `performance.now()` gives sub-millisecond resolution but is relative to page load, and browsers deliberately coarsen it against timing attacks.

Seconds, milliseconds, microseconds and nanoseconds, in both directions.
Milliseconds ConverterThe 13-digit form — what `Date.now()`, `System.currentTimeMillis()` and most of Java and JavaScript speak — converted both ways, with the seconds value beside it.
Nanoseconds ConverterThe 19-digit form — Go's `UnixNano`, Prometheus, InfluxDB, OpenTelemetry — with a warning about the precision JavaScript quietly loses on the way.
Unix Timestamp ConverterPaste a timestamp and get the date; paste a date and get the timestamp. Seconds, milliseconds, microseconds and nanoseconds are detected from the digit count, and the guess is shown so you can override it.
Timestamp to DateOne field, one answer — the timestamp as a date and time in your zone, in UTC, and in about thirty other encodings you might need to paste somewhere.
